[jQuery] Periodical updater using Json in Jquery?

[jQuery] Periodical updater using Json in Jquery?


I'm grabbing an update from a json file, but I want to have it update
perodically to the screen, overwriting what it found before... sort of
like Prototype's Ajax Updater. Is this possible in Jquery? I scoured
the groups to but only found a digg spy thing, which is sort of what
I'm looking for but it was dated for 2007, so there's gotta be
something new or is that it?
Please help. TIA
